A 10b DAC with multicurrent path control and the weighted transconductors reduces the data driver size by 30%, compared with the previous art. Coarse and fine interpolation provides two additional bits in the proposed technique. The DAC is fabricated in a 90nm CMOS process and consumes 1.1 μA of static current per a channel. INL, DNL and minimum DVO are 0.8LSB, 0.37LSB and 6.5mV, respectively, in 20KΩ and 30pF of the load condition.
